Recommended: Human Gut Microbiota
What is Gut Microbiota? Community small microorganism that inhabits the entire length of the gastrointestinal (GI) tract is known as gut microbiota. The gut microbiota is mainly composed of bacteria from two major phyla: Bacteroidetes and Firmicutes are the two major phyla that occur inside the gut but there are some less abundant phyla also present such as Actinobacteria, Proteobacteria, Euryachaeota, and Verrucomicrobia (1)(2). The density and composition of the human gut microbiota is described in Figure 1. These gut microbiotas possess numerous other metabolic abilities and activities, such as changing diet and other lifestyle factors can alter gut microbiota balance (dysbiosis) and cause increase intestinal permeability (3,(4)(5).(Figure
Its morphology consists of a rod-shaped gram negative bacteria that is commonly found in soil, water, vegetation, human intestines, as well as the intestines of animals. Its presence can be good or bad. The family Enterobacteriaceae consists of a large number of genera which are genetically and biochemically related to one another. Escherichia coli is a component of the family. This bacterium was discovered by a German pediatrician and bacteriologist named Theodor Escherich in 1885.
Enteric bacteria are major microorganisms that colonise human’s gastrointestinal tract- a long tube containing specialised sections such as the mouth, oesophagus, stomach, intestines, rectum and the anus. Gut bacteria make up approximately 95 percent of the total cells in the body, with the colon containing the densest microbial communities (Gibson, Rastall and Fuller 2008: 52). Human gastrointestinal tract consists of 100 different prokaryotic species, and with two bacterial species, firmicutes and bacteroicidetes dominating them (Brooker et al. 2011: 559).
There are numerous types of bacteria that can be found in every environment. Each bacterium has different morphology which includes shape, texture and pigment production. These bacteria also have different food requirements which are important in being able to identify a microorganism. Microorganisms are a diverse group containing all bacteria a single cell prokaryotic organism that is found in every type of environment, archea single cell microorganism that lacks nuclei and almost all microorganisms are protozoa a unicellular eukaryotic organism. By identifying the causative agent of a bacterium within an individual, an antibiotic can be developed to prevent health issues. Microorganisms are also used to make certain food products for human consumption. An example of this would be the production of yogurt. It has probiotics that help with digestive abnormalities amongst other things. Probiotics are microorganisms that are consumed to provide health benefits in the body. Probiotics work by replacing the disturbed microbe with ones that are useful to digest. With the methods that wer...
The digestive system otherwise known as the gastrointestinal tract (GI tract) is a long tube which runs from the mouth to the anus. It operates to break down the food we eat from large macromolecules such as starch, proteins and fats, which can’t be easily absorbed, into readily absorbable molecules such as glucose, fatty acids and amino acids. Once broken down, these molecules can cross the cells lining the small intestine, enter into the circulatory system and be transported around the body finally being used for energy, growth and repair.
To understand the human gut health and aetiology, the first step is to understand the gastrointestinal (GI) microflora and its distribution through the digestive system [2]. The human GI tract is inhabited by trillions of microorganisms, which together is known as the microbiota [5]. These microorganisms come from both archeal and bacterial domains. Bacteria are the predominant kingdom of organisms and it is composed mainly by five bacterial phyla: Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria and Verrucomicrobia [3]. The great majority of mammalian gut microbiota belongs to the three phyla: the Gram-negative anaerobe Bacteroidetes, the Gram-positive Actinobacteria and Firmicutes [5].
It measures about 1.5m in length, and 6.5cm in diameter, wrap around the small intestine, in a shape of an arch. It is made up of caecum, colon, rectum, appendix, anal canal and anus. About 90% of water is re-absorbed here, which is one of its major function. There are also bacteria in the large intestine that converts protein to amino acid. These bacteria produce gas, acid and vitamin B &K by breaking down amino acid. These vitamins are absorbed here. The content of the large intestine changes to a semi solid state called faeces due to water re-absorption. (Tortora G. and Derrickson B.
E Coli is a Gram negative rod shaped bacteria that has a cell membrane and cell wall protecting its DNA. On the outside of each E Coli cell, there are small tails called flagella. E Coli respires anaerobically, which means that it doesn't need oxygen to respire (breathe). It feeds on undigested nutrients in the guts of mammals, including humans and ruminants such as cows, sheep, and goats.
Diabetes is a metabolic disease, that causes a person to have high blood pressure. There are two kinds of diabetes, type 1 and type 2. Type 1 is the loss of insulin producing cells, leading to a deficiency of insulin. Type 2 diabetes is where the person is insulin resistant. Insulin is a peptide hormone, which causes cells to absorb the various glucose it requires. Type 2 diabetes is the most widespread endocrine disease worldwide. Metagenome wide associated study took on a study that was based on the determination of type 2 diabetes and relationship to gut microbial by using the deep shot gun sequencing of the gut microbial. The study consisted of 345 Chinese's individuals that were used to help find any relationships. 60000 type 2 diabetes associated markers were used and linked to type 2 diabetes. Gut microbes are living organisms that live in the gut and the digestive tract. Patients with type 2 diabetes were characterized by a moderate degree of gut microbial symbiosis. Symbiosis is a interaction between different microbial organisms, there are various types of symbiosis such as mutalistic, parasitic and communalistic. The abundance of butyrate producing bacteria as well as the opportunistic pathogens were determined as well. Enrichment of microbial functions due to sulphate reduction and oxidative stress resistance was found. Further studies were also performed with addition of individuals to the study. Gut microbial markers may be useful for classifying type 2 diabetes.
The human gut contains a huge diversity of bacteria and the microbiota, which is crucially important for maintaining human health. According to Greiner et al, the gut microbiome plays an important role as a regulator to modulate human’s metabolism when there is a change in the environment. It is because that the gut microbiome is composed of many different bacterial species, and thus it is a multicellular organ with a metabolic function (2011). Despite the huge diversity of the gut microbiome, there are only three groups of bacteria are dominated in human gut microbiome, which include Firmicutes, Bacteroidetes, and Actinobacteria (Greiner et al 2011).
Our body consists of 90% of bacteria. That means that for every cell that we have in our body, we have 9 bacterial cells living along with it. Granted that most of the bacteria live inside the intestinal tract, but without a proper immune system keeping the digestive system in check, we would not be properly digesting food or have healthy bodies.
The human microbiome is the collective ensemble of a wide diversity and density of living micro organisms found both in and on the human body. The exploration of this vast ecosystem is an exciting and innovative topic of discussion in recent times. In fact, its relevance has become so important as of late that it has taken its place at the top of 21st century

Microbes are microscopic life forms, usually too small to be seen by the naked eye. Although many microbes are single-celled, there are also numerous multi-cellular organisms. The human body has 10-100 trillion microbes living on it, making it one giant super-organism. Since the first link between microbes and diseases was made, people have been advised to wash their hands. Scientists, however, have recently started to investigate more closely how the microbes that call the human body home affect our health. While some microbes cause disease, others are more beneficial, working with our bodies in many subtle ways.
Introduction to Macrobiotics Macrobiotics are one of the many alternative diets that have gained popularity in the United States over the last couple decades. Michio Kushi introduced macrobiotics to New York City in the 1970's. Proponents of macrobiotics contend that it is not merely a diet, but a philosophy that, if properly observed, will ensure emotional, physical, spiritual and mental well-being. Good physical health is necessary before emotional, physical, and spiritual wellness can be cultivated. See Foundation for the Macrobiotic Way.
Knowledge is power when discussing the classes you have taken in college and how it affects your everyday life. Microbiology is one of those important classes where although for a majority of majors you do not have to take it and therefore will not learn the information discussed in it, other majors such as biology and nursing require you to take it. They will require you to take it because you will encounter some of the information being taught in it in the work field. As a nurse practitioner I have worked in the field with many patients who were diagnosed with Leprosy, Escherichia coli, Salmonella and other bacterial diseases. All of these diseases that I have encountered in patients were ones I was familiar with due to learning about them as a student in microbiology at CSUB. My children plan on
